Figure 1. Protection by peptide HH2 against an invasive Staphylococcus aureus infection in mice, compared to a negative control peptide HH17.

Mice were pretreated with saline (control) or 4 mg/kg peptide (IP) in saline, and infected 4 hours later with approximately 1.0×10⁹ CFU of S. aureus. Twenty-four hours post infection, mice were euthanized and the peritoneal lavage taken, and plated on Mueller Hinton agar. The graph is representative data from a series of 2 independent experiments. *represents p<0.05.
